Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of liquid crystal indicator.
Background technology
Liquid crystal indicator (Liquid Crystal Display, LCD) has advantages of that image quality is good, volume is little, lightweight, low driving voltage, low-power consumption, radiationless and manufacturing cost is relatively low, occupies an leading position at present in flat pannel display field.Liquid crystal indicator is applicable to being applied in the multiple office automations such as desk-top computer, palmtop computer, personal digital assistant (Personal Digital Assistant, PDA), portable phone, TV box and audio-visual equipment very much.Display panels is the chief component of liquid crystal indicator.Conventionally, display panels comprises array base palte, colored filter substrate and liquid crystal layer, and liquid crystal layer is arranged between array base palte and colored filter substrate.Wherein, array base palte and colored filter substrate are bonding by sealed plastic box.
Image retention is one of remarkable defect that liquid crystal indicator exists now, and so-called image retention refers to the same fixing picture of the long-time demonstration of liquid crystal indicator, and when Picture switch arrives next picture, meeting is the image of a residual upper picture indistinctly.The reason that image retention produces is mainly in DC offset voltage and liquid crystal layer, to have ion-type impurity owing to existing between array base palte and colored filter substrate.Ion-type impurity mainly enters liquid crystal layer from sealed plastic box and alignment film, for example, if before sealed plastic box is not also solidified completely, if come in contact between sealed plastic box and liquid crystal, can cause the ion-type impurity in sealed plastic box to enter liquid crystal layer.
Current aligned twisted enhancement mode (Pattern Enhanced Twist, PET) as a kind of novel wide viewing angle technology of liquid crystal indicator, there is wider visual angle and lower operating voltage, it is comprised of special three-electrode structure, be that pixel electrode and one of them public electrode are positioned on array base palte, and pixel electrode is positioned at the below of public electrode, centre is separated by insulation course, another one public electrode is positioned on colored filter substrate, wherein the pixel electrode of array base palte and public electrode form fringe field, the pixel electrode of array base palte and the public electrode of colored filter substrate form plane electric fields.Conventionally, on array base palte, the voltage of public electrode remains unchanged, and only changes the voltage of pixel electrode, upper and lower symmetrical centered by the magnitude of voltage of the waveform that makes voltage on pixel electrode on public electrode.Due in real work, the driving voltage that is applied to pixel electrode is completely upper and lower symmetrical centered by the magnitude of voltage on public electrode, thereby generation DC offset voltage, and ion-type impurity is with certain electric charge, and the electrode of the both sides public electrode of liquid crystal layer immobilizes, ion-type impurity is easy to assemble on public electrode like this, on array base palte or colored filter substrate, easily cause ion residues, can affect the orientation of place, ion-type impurity present position liquid crystal molecule, thereby cause the generation of image retention, make liquid crystal indicator occur showing bad phenomenon.
In order to eliminate afterimage phenomena, prior art adopts following two kinds of methods conventionally: a kind of method is to select the oriented material of low resistivity, and to accelerate the release of ion, the liquid crystal material that selection is difficult for dissociating simultaneously, to reduce the introducing of ion-type impurity.Yet due to the restriction of making technology, fundamentally DC-offset correction voltage, more can not thoroughly control the generation of afterimage phenomena.Prior art another kind method is the public electrode on array base palte to be arranged on to the below of pixel electrode, the two ends of liquid crystal layer are pixel electrode and public electrode like this, and driving voltage can provide alternating current for pixel electrode, ion-type impurity is relatively not easy to assemble above pixel electrode, thereby can improve afterimage phenomena.Yet while adopting this kind of design, being positioned at public electrode on array base palte can be near data line, and public electrode and data line be arranged in parallel, can produce stray capacitance.In order to reduce the impact of stray capacitance on liquid crystal display; just need to be at public electrode surface coverage one deck over coat (protective seam); and the needed exposure ability of over coat is higher; time shutter is longer; so not only can increase cost, also can increase and produce the time that liquid crystal indicator is used.
